Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
800g lamb shoulder or leg, bone-in or boneless
500g potatoes, peeled and cut into medium chunks
3 garlic cloves, peeled and lightly crushed
2 sprigs fresh rosemary
4 tablespoons olive oil
1 ½ teaspoons salt
1 teaspoon black pepper
1 teaspoon dried oregano (optional, for extra flavor)
120 ml water or light vegetable broth
Directions
Preheat your oven to 180°C. Lightly grease a large baking dish with olive oil.
Prepare the potatoes by peeling them and cutting them into even-sized chunks to ensure uniform cooking.
Pat the lamb dry using paper towels to help it brown better during roasting.
Place the lamb in the center of the baking dish and arrange the potatoes around it.
Add crushed garlic cloves and rosemary sprigs evenly over the lamb and potatoes.
Drizzle olive oil generously over everything, ensuring the potatoes are well coated.
Season with salt, black pepper, and oregano if using.
Pour water or broth into the base of the dish to keep the meat moist during cooking.
Roast in the oven for 1 hour to 1 hour and 30 minutes, depending on the size of the lamb cut.
Turn the potatoes and baste the lamb with pan juices every 25–30 minutes for even flavor and browning.
Once the lamb is tender and golden and the potatoes are crisp on the outside, remove from the oven.
Let the meat rest for 10 minutes before slicing. Serve warm with the roasted potatoes and pan juices spooned over the top.

Variations
You can customize this dish in several ways. For a stronger herbal flavor, add thyme or sage along with rosemary. If you prefer a citrus note, include slices of lemon placed around the lamb before roasting. You can also add vegetables such as carrots or onions to the baking dish for extra sweetness and depth. For a richer flavor, marinate the lamb for a few hours in olive oil, garlic, rosemary, and salt before cooking. If you want a lighter version, reduce the olive oil slightly and use more broth to keep the dish moist.
Storage/Reheating
Leftovers should be stored in an airtight container in the refrigerator for up to 3 days. To reheat, place the lamb and potatoes in an oven-safe dish, cover lightly with foil, and warm at 160°C for about 15–20 minutes until heated through. You can also reheat smaller portions in the microwave, but the oven method helps preserve texture better. If freezing, store the lamb separately from the potatoes for best results and consume within 2 months.
